Fig. 4: Observation of tilted surface dispersions of antichiral surface states.
From: Topological antichiral surface states in a magnetic Weyl photonic crystal
a–c Measured surface dispersions of the A-type surface with fixed a kz = 0π/h, b kz = 0.38π/h, and c kz = π/h, respectively. The white (green) lines represent the simulated bulk (surface) dispersions, respectively. The orange and purple spheres represent the projections of the frequency-shifted WPs with opposite topological charges. d–f The same as a–c but for the B-type surface.
